Answer:
see below
Step-by-step explanation:
g(x) = 3 − x^2
(a)g(30) = 3 - 30^2 = 3 - 900 = -897
(b)g(3)= 3- 3^2 = 3-9 = -6
(c)g(−1) = 3 - (-1)^2 = 3 - 1 = 2
(d)g(0.5) = 3 - (.5)^2 = 3 - .25 = 2.75
Answer:
For 4 seconds the projectile will be in the air.
Step-by-step explanation:
The function f(x) = –10(x)(x – 4) represents the approximate height of a projectile launched from the ground into the air as a function of time in seconds, x.
Now, if the projectile stays for x seconds in the air then after x seconds its height will be zero.
Hence, 0 = - 10x(x - 4)
⇒ x = 0 or x = 4
Now, x cannot be 0 as at time = 0 the projectile starts its motion.
So, for 4 seconds the projectile will be in the air. (Answer)
ANSWER: -9
I used a graphing calculator.
Sorry if this is incorrect. Weird calculator I have.
Probabilities are used to determine the chances of events.
The probability P(the stock performs below average|domestic) is 0.109
<h3>How to calculate the probability</h3>
Let A represent the number of stocks that performs below average
B represents the number of domestic stock
From the table, we have:
n(A n B) = 55 i.e. domestic stocks that performs below average
n(B) = 505 i.e. all domestic stocks
The probability is then calculated as:
This gives
Hence, the probability P(the stock performs below average|domestic) is 0.109
